Purpose: This study aims to develop a quality optimization methodology for servo press commemorative coin manufacturing using response surface methodology and design of experiments.
Methods: A full factorial design (27 experiments) and a D-optimal design (17 additional experiments) were conducted for three factors: compressive load, adjustment speed, and deceleration distance. Quadratic response surface models were constructed using the Canny edge-based clarity standard deviation as the response variable.
Results: Statistical performance significantly improved, with the F-statistic increasing from 11.07 to 24.97 and the p-value decreasing from 1.65×10⁻⁵ to 1.75×10⁻¹². Optimization identified the optimal process conditions that achieved maximum clarity.
Conclusion: The integrated approach successfully established a robust quality prediction model for servo press manufacturing with minimal experimentation.
